Astrophi: a software package for complex modelling of astrophysical objects dynamics with using of hybrid architecture supercomputers

There is a new hydrodinamical code AstroPhi for modeling of astrophysical objects dynamics on hybrid supercomputer proposed. This software package is optimized for using with Intel Xeon Phi calculations accelerators. AstroPhi code is based on combination of Godunov and author’s FlIC numerical methods for solving of gas dynamics equations. Fast Fourier Transform was used for Poisson equation solution. AstroPhi was tested on gas dynamics problems, Poisson equation solution and classical gravitational gas dynamics problems. The results of this tests and results of gravitational collapse of astrophysical objects modeling proposed. The results of AstroPhi scalability based on Intel Xeon Phi runs are shown.
